In close collaboration with the Office for Historical Monuments, the new terrace roof of the Rutlihaus restaurant was constructed as a delicate and elegant low-height membrane structure, blending in perfectly with the landscape: the slightly inclined roofs and the spruce wood make a pleasant and refined combination. The canopy consists of five linked gables. Weather and UV protection is provided by a translucent membrane SEFARR Architecture TENARAR Fabric 4T40HF,
which has a light transmission of approximately 40% and allows the transmission of a mild and pleasant fraction of the sunlight. This makes the roof function like an airy pergola.
